How do I make my GL450 air conditioning colder?

For starters, use a sun-blocking shade in the windshield while you’re parked, or look for a shady parking spot. Closing all the passenger vents in your car can help redirect cold air toward you, cooling you off faster. Still need more chill? Head to Firestone Complete Auto Care for an A/C performance check and recharge.

Why do I get hot air from my GL450 A/C?

Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.

What can cause an A/C system leak?

To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your GL450’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does my GL450 A/C use gas?

GL450 air conditioning systems don’t use gasoline as a direct fuel source. However, they do rely on engine power, which can indirectly affect your vehicle’s gas mileage.

Why does the A/C in my GL450 smell like vinegar?

If a vinegar-like odor comes from your A/C, bacteria growth could be the culprit. Moisture accumulation in the air conditioning system of your GL450 creates a breeding environment for microorganisms.

Why does my GL450’s A/C only work when the car is moving?

If your A/C only works when the vehicle is moving, there could be a problem with part of your GL450’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

A/C Repair Service for Your Mercedes-Benz GL450

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Is that a hot stove? Nope, just your steering wheel. Your skin sticks to the driver’s seat. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz GL450 A/C?” Firestone Complete Auto Care — that’s who! We know our way around Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 2009 Mercedes-Benz. Come to your local Firestone Complete Auto Care in your Mercedes-Benz GL450

In this A/C performance inspection, we’ll check out the current condition of your 2009 Mercedes-Benz GL450 A/C system to determine whether repair work is needed. This check includes a visual inspection, performance test, and pressure and leak test. If we suspect a leak, we’ll send a U/V dye through your A/C system or use a “sniffer” to find the leak. A "sniffer" is a machine that's run along parts of your Mercedes-Benz GL450 A/C system that can identify points where refrigerant fumes could be escaping the system. If there's a leak, we'll find it and fix it.

GL450 A/C Recharge

Let's say we repair your 2009 Mercedes-Benz GL450 A/C system. We will also perform an A/C evacuation and recharge. To do this, one of our technicians will remove the refrigerant in your A/C system (if there is even any left to remove). Next, they will evacuate the system according to Mercedes-Benz's recommendations. To finish, we’ll add new refrigerant to recharge the A/C system, and after one final test to be sure the system is cooling properly, you’re good to go. Our technicians are trained to efficiently perform 2009 Mercedes-Benz GL450 A/C recharges.

Other Mercedes-Benz GL450 A/C Problems

Warm air isn't the only Mercedes-Benz GL450 A/C problem you may encounter. Other common A/C problems include weak airflow, which could mean you have a compromised seal, mildew or mold buildup, a loose or damaged hose, or a ventilation fan that needs to be replaced. If your A/C system blows cold air first but then it turns warm, this may suggest a leak, a blown fuse, or a damaged compressor clutch. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2009 Mercedes-Benz GL450? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our trained technicians will do what they can to solve your A/C problems. We’re here to help you get back on the road in your GL450 — without all the sweat puddles!
